ToaZZ whomI it may concern:

-Be it known that; I, ANDREAS HANS J .toon APPELT, manufacturer, a ci tizen of lDen mark, and a resident of Copenhagen, Denmark, have invented certain new and useful Improvements in Bullet-Proof Shields, of whichI the following is a specification.

.My invention relates to what is modernlyl known as a bullet-proof shield whichafforosan e'eetive protection against project On account of thelstrong explosive power of smokeless powder and of the small caliber vof modern guns it is Well known that such a high speed and greatpower of penetration are attained that no covering material such as leather, wood, steel, risc., having dimensions which permit of carrying the shield or garment made therefrom on the body, olt'ers ef- Aiective resistance against the penetrability of the projectile. The object of my invention is to provide suoli a bullet-proof shield..

My invention tothis end consists of 'material for bullet-proof shields which is composed ofa thiv back-plate or mount of hard metal on which is supported a series of closely ar ranged knife edged metallic strips, the thick v backs of the same resting against the backplate and the thin knife-edges being presented outwardly and provided with a protecting facing of suitable fabric so that thestrips are inelosed between the back-plate and facing.

In the dra\\'ings,l"rignre 1 is a transverse sect-ien showing the construction ot' the inaterial, and` Fig. 2 is a face-view, the facing being removed.

lSimilar letters of reference indicate corre.

- ing of a plate-metal mount, knife-edged mrsspending parts.'

The bnek-plateor mounta is formed of thin plate steel or other suitably hard metal and is covered over with a layer of preterabl y elastic or soft material, such as rubber, leather,

cardboard, the. The thick rear edges c of -Lhe knife-ed|fed metallic stri c rest against the inner surface of the plate metal mount a so that the sharp front. edges c2 of the same will be presented outwardly. The backs of the stri psc are arranged closely together and preferably in contact, so that the knife edges 'c9- tviil be disposed at very small intervals.

' 'l`iie knife-edges are covered over bya facing -z of linen, vcanvas or other suitable fabric so Y l as to protect the satneand impart a. finish toi the materiai. It vis obvious that the knife-l edged stripsr may be disposed in other rela 55 may be provided, the kniteedged strips of one layer extending across those of the'other 6o layer. When a bullet strikes a shield com- 'E posed of this material the same is cuthpinto small pieces by means of the knifeedges. and' v as the pieces pass inwardly they meet with still greater resistance by reason of the grad- 65 ual rearward thickening of 'the strips so that their force is usually spout Vere they reach the back-plate or mount a, which, however, offers further resistance in case any pieces ot' the 'bullet should reach it.

By reason of the structural arrangement of the component partsv of vthe bulletproof ma terial the same'possesses a certain degree ofr flexibility so that it can be bent to conform to the body of the wearer.

7s Of course in forming a shield for the body it may be found necessary to variously r range the knife-edged strips, some extending one way and some another.

Having thus described my invention,-I 8o claim as new and desire to secure by Letters Patent,-

1. Material for bullet/proof shields consistn ing of a plate-metal mount, and knife-edged metallic strips arranged closolytogether and 85 resting at their backs against the inner sul` face of the mount, with their knife-edges presented outwardly, substantially as set forth.

2. Material for bullet-proof shields consisttaIlic strips arranged closely together and resting at their backs against the inner snrface of the ino-tint, with their knife-edge prosented outwardly,and a suitable facing,v-

ering the knifeedges, vsubstantially asset 95 forth. d

In testimony that I claim the foregoing as my'invention I have signed my name in pres k ence of two subscribing witnesses.
